The main shaft 14 is mounted inside the hollow drive shaft 6 of the housing via the bearing II 43.

[0032] The main shaft 13 is a cantilever shaft within the cantilever housing cavity. The end face of the mechanical seal 7 is fixed to the housing connecting seat 8. The rotating ring of the mechanical seal 7 rotates together with the main shaft 13, and the fixed ring is connected to the housing connecting seat 8 and rotates with the cantilever housing. The main shaft heating rotary seal 1 connected to the end of the main shaft 14 is connected to a heat source. The heat source heats or cools the main shaft 14 through the inlet and outlet of the main shaft heating rotary seal 1, realizing the heating, rotation, and sealing of the main shaft. The main shaft 14 acts on the bearing support 4 through two bearings II 43, the drive shaft 6, and the bearing 3. The bearing support 4 is fastened to the base 21. The load of the main shaft 14 is transmitted to the base 21 in sequence through the two bearings II 43, the drive shaft 6, and the bearing support 4. All loads are borne by the support 21 to ensure stable operation.

[0034] The scraping end of the blade 13 is an arc shape corresponding to the scraping part of the inner wall of the hemispherical body, and the running trajectory of multiple scraping blades 13 covers the entire inner wall of the inner spherical shell 12.

[0035] The scraper blade 13 located in the middle part of the main shaft 14 has an inclined plate on one side. The inclined plate forms an angle α of less than 90 degrees with the tangent of the rotation trajectory, which rotates and compacts the cracks on the upper surface of the filter cake after filtration.

[0036] The gap between the scraping end of the blade 13 and the inner wall of the inner spherical shell 12 is 0.5-10 mm, with an optimal gap of 2-5 mm, and 2 mm in this example. The inner wall of the hemispherical shell is scraped over its entire surface by the main shaft 14 and the scraping blade 13 on it.

[0037] In this example, the bottom edges of the hemispherical cavity and the conical cavity are connected by a flange or chuck 12 to form a structure with one end conical and the other end hemispherical. A discharge port is opened at the conical end, and a discharge valve 5 is installed on it.

[0038] The hemispherical cavity consists of a hemispherical body and a transition section. From the inside out, it comprises a hemispherical inner liner 12, a hemispherical heating layer 11, and a hemispherical insulating outer shell 10. It is used for heating, drying, or crystallizing materials. A material inlet 33 and a cleaning inlet 34 are located on the transition section.

The hemispherical heating layer 11 of the hemispherical cavity is connected to a heat source for heating; the hemispherical insulating outer shell 10 uses existing insulation materials to better maintain the temperature of the hemispherical cavity, facilitating drying or crystallization.

[0039] The hemispherical cavity is smooth and free of dead corners, with good geometric symmetry, making it easy to achieve full-area scraping, which is beneficial for heat transfer and drying. This invention also includes a sampling port 39, a temperature detection port 40, and a pressure detection port 41 on the hemispherical cavity. An online sampler is installed on the sampling port 39 for real-time sampling; the temperature detection port 40 and pressure detection port 41 are used for temperature and pressure detection, respectively.

[0040] The conical cavity sidewall is composed of a filter layer 19, a filtrate recovery jacket 18, a heating layer 17, and an insulation shell 16 arranged sequentially from the inside to the outside. A liquid recovery chamber is formed between the filter layer 19 and the filtrate recovery jacket 18. A filtrate outlet 31 and a vacuum connection port 38 are respectively opened on the filtrate recovery jacket 18 at the bottom of the conical cavity. 17 is a heating jacket, a half-pipe, or other heating structure, and 16 is an insulation shell.

[0041] Both the hemispherical heating layer 11 and the heating layer 17 are provided with a shell heat source inlet 32 ​​and a shell heat source outlet 30 (the figure shows a cavity with a hemispherical shape as an example). The heat source is circulated through the shell heat source inlet 32 ​​and the shell heat source outlet 30 for heating or cooling the cantilever shell.

[0042] A discharge valve 5 is installed at the bottom of the conical cavity, through which solid powder is discharged; the filtrate of the conical filter layer 19 is discharged through the filtrate outlet 31, and the air inside the shell is extracted through the vacuum connection port 38 during drying.

[0043] The filter layer 19, i.e. the inner wall of the conical cavity, is a conical filter plate or filter cloth. A vibrator 37 and a backflush port are also provided on the outer wall of the conical cavity. The backflush port is connected to an air source. The filter cake attached to the inner wall of the conical cavity is vibrated by the vibrator 37 and / or backflushed by the backflush port.

[0044] The conical cavity allows for a large volume and large filtration area, which is beneficial for solid-liquid separation. A powder discharge valve is installed at the bottom of the inverted conical cavity to discharge the material through vibration and backflushing.

[0045] The conical cavity described in this invention can be designed as a cone or a transitional flat-bottomed cavity, depending on the material being processed. By adjusting the height and diameter of the conical or flat-bottomed cavity, the ratio of heating area to filtration area can be arbitrarily set to meet the requirements of different process materials.

[0046] The method of using the ball-cone shaped multifunctional machine of this utility model includes the following steps in the filtering, washing, and drying processes:

[0047] S1: In the initial stage, the drive shaft 6 is driven by the shell flipping device to rotate the cantilever shell to the position of the conical cavity below. The solid-liquid mixture falls into the conical cavity through its feed port 33 for pressure filtration or vacuum filtration to achieve solid-liquid separation. The separated solids remain in the conical cavity, and the liquid is discharged out of the shell through the liquid recovery chamber.

[0048] S2: The material washing liquid is then introduced into the conical cavity through the washing port 34 to wash the material and perform secondary filtration or pressure filtration. The separated solids remain in the conical cavity, while the liquid is discharged from the conical insulation shell 16 through the liquid recovery chamber, resulting in a qualified filter cake that is ready for drying.

[0049] S3: After washing n times according to step S2, n≥1, the number of washing times depends on the production process requirements. Press the material dry to obtain a qualified filter cake and wait for it to dry.

[0050] S4: Drive the transmission shaft 6 through the shell flipping device to rotate the cantilever shell 180 degrees, so that the conical cavity is upward and the filter cake to be dried falls into the lower hemispherical body by gravity.

[0051] S5: Turn on the vibrator 37 and blow gas through the backflush port to pass the filter cake attached to the inner surface of the conical cavity and let it fall into the hemispherical body;

[0052] S6: The cantilever shell is heated and evacuated, and the material is stirred and dried by the main shaft 14 driving the blade 13 to obtain a qualified dried product. The material is automatically pushed out of the cantilever shell by the scraping blade 13 of the main shaft, completing one working cycle.

[0053] If crystallization is required, first flip the conical cavity in the cantilever shell to the top and the cavity with the hemispherical shape to the bottom. The crystal cleaning solution enters the cavity with the hemispherical shape through the feed inlet 33. Turn on the stirring and scraping device and carry out the heating and cooling process to complete the crystallization. Then carry out the S1 to S6 filtration, washing and drying steps to complete the entire process of crystallization, filtration, washing and drying.

[0054] Example 2: This example differs from Example 1 in that the cantilever shell in this example is composed of a hemispherical cavity and a flat-bottomed cavity connected together. The hemispherical cavity and the flat-bottomed cavity are connected by a flange or chuck 12 to form a structure with one end round and the other end flat. A discharge port is opened at the flat end, and a discharge valve is installed on it.

[0055] The filter layer on the side wall of the flat-bottomed cavity is a filter plate, which uses existing microporous filter media; the gap between the scraping end of the scraping blade and the inner wall of the hemispherical body is 2mm.

[0056] This example of a multi-functional ball-cone shaped machine is used for crystallization, filtration, washing, and drying. Its operating method is as follows:

[0057] First, crystallization is carried out by flipping the flat-bottomed cavity in the cantilevered shell to the top and the cavity with the hemispherical shape to the bottom. The crystal cleaning solution enters the cavity with the hemispherical shape through the feed port. The stirring and scraping device is turned on, and the heating and cooling process is carried out to complete the crystallization. Then, the filtration, washing and drying steps S1 to S6 in Example 1 are carried out to complete the entire process of crystallization, filtration, washing and drying.

[0058] Example 3: This example differs from Example 1 in that the filter layer on the side wall of the conical cavity in this example is a conical filter cloth, and the gap between the scraping end of the scraping blade and the inner wall of the hemispherical body is 10mm.

[0059] Example 4: This example differs from Example 1 in that the filter layer on the side wall of the conical cavity in this example is a conical filter cloth, and the gap between the scraping end of the scraping blade and the inner wall of the hemispherical body is 3mm.

[0060] Example 5: This example differs from Example 1 in that the filter layer on the side wall of the conical cavity in this example is a conical filter cloth, and the gap between the scraping end of the scraping blade and the inner wall of the hemispherical body is 2mm.

[0061] Components not described in detail in this application are all existing conventional technologies and will not be described further here.
